Electrophysiology

The cardiac subspecialty of electrophysiology (EP) diagnoses and treats arrhythmias. This includes use of pacemakers to treat bradycardia, implantable cardioverter defibrillators (ICD) for tachycardia, heart failure and patients at risk of sudden cardiac arrest, and cardiac ablation treatments to treat heart rhythm disorders.

Medtronic heart rhythm technologies on full display at AF Symposium 2025

Cardiologists shared updated data on Medtronic's ICM and PFA offerings during AF Symposium 2025 in Boston. 

The Medtronic SelectSecure MRI SureScan Model 3830 cardiac lead already gained FDA approval for His-Bundle pacing back in 2018. Now, the lead is also approved for left bundle branch area pacing, providing users with another option when treating patients for bradycardia. According to Medtronic, this marks the first time the FDA has approved a device for this indication.

New research highlights rising interest in LBBAP
